Lightweight luggage shell

ABSTRACT

A luggage shell is formed of a top plate, a bottom plate, and two side plates, which are all provided with a number of pits for reducing the weight of the luggage shell. The pits are arranged at interval in rows. The top plate, the bottom plate and the side plates are further provided with a plurality of ribs which are located between two adjacent rows of the pits for reinforcing the structural strength of the luggage shell.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates generally to a luggage, and moreparticularly to a shell of the luggage.

[0003] 2. Description of Related Art

[0004] As shown in FIG. 1, a prior art luggage comprises a shell 10, asleeve 11 fitted over the shell 10, a plurality of casters 12, and apull handle 13. The shell 10 of the prior art luggage is rather durable;nevertheless it is rather heavy. In general, the consumers prefer adurable and lightweight luggage to a durable and heavy luggage.

BRIEF SUMMARY OF THE INVENTION

[0005] The primary objective of the present invention is to provide aluggage shell which is durable and light in weight.

[0006] The luggage shell of the present invention is formed of a topplate, a bottom plate, and two side plates. The top plate, the bottomplate and the side plates are provided with a number of pits which arearranged equidistantly and are intended to reduce the weight of theluggage shell. The top plate, the bottom plate and the side plates arefurther provided with a plurality of ribs for reinforcing the structuralstrength of the luggage shell.

[0007] The features and the advantages of the present invention will bemore readily understood upon a thoughtful deliberation of the followingdetailed description of a preferred embodiment of the present inventionwith reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0014] As shown in FIGS. 2-6, a luggage of the preferred embodiment ofthe present invention comprises a shell 20, a sleeve 30 fitted over theshell 20, an expandable pull rod 32, and a plurality of casters.

[0015] The luggage of the preferred embodiment of the present inventionis characterized by the shell 20 which is formed of a top plate 22, abottom plate 23, and two side plates 24 which are disposed between thetop plate 22 and the bottom plate 23. The top plate 22, the bottom plate23 and the side plates 24 are provided with a number of pits 21 whichare arranged equidistantly in rows and are intended to reduce the weightof the shell 20.

[0016] In order to enhance the structural strength of the shell 20, thetop plate 22 is provided with a plurality of ribs 25 (not shown in thedrawings) which are located between two adjacent rows of the pits 21.The pits 21 and the reinforcing ribs 25 are made integrally with the topplate 22. Similarly, the bottom plate 23 is provided with a plurality ofribs 25 which are located between two adjacent rows of the pits 21. Thepits 21 and the ribs 25 are integrally made with the bottom plate 23.The two side plates 24 are also provided with a plurality of reinforcingribs 25 which are located between two adjacent rows of pits 21. The pits21 and the ribs 25 are integrally made with the side plates 24.

[0017] In light of the pits 21, the shell 20 of the present invention islight in weight. In addition, the structural strength of the shell 20 ofthe present invention is reinforced by the ribs 25.

[0018] The embodiment of the present invention described above is to beregarded in all respects as being merely illustrative and notrestrictive. Accordingly, the present invention may be embodied in otherspecific forms without deviating from the spirit thereof. The presentinvention is therefore to be limited only by the scope of the followingclaim.
